In a significant advancement for the energy sector, researchers have unveiled a mathematical programming model designed to optimize ammonia co-firing networks, a development that could reshape how industries approach decarbonization. This innovative work, led by Raymond R. Tan, highlights the potential of green ammonia as a viable fuel alternative, particularly in the quest for deep decarbonization across various sectors including industrial operations, transportation, and power generation.
Green ammonia, produced using renewable inputs, stands out as a carbon-neutral energy carrier, presenting fewer challenges in handling and storage compared to its counterpart, hydrogen. However, the transition to pure ammonia in combustion systems necessitates extensive retrofitting or new investments, primarily due to its distinct combustion characteristics, such as altered flame speed and air-fuel ratios when compared to natural gas. This is where Tan’s research comes into play.
By allowing for the blending of ammonia with natural gas, the study proposes a pathway for partial decarbonization that minimizes the need for significant modifications to existing combustion systems. “The flexibility of blending ammonia with natural gas offers a pragmatic approach for industries aiming to reduce their carbon footprint without the immediate need for costly retrofits,” Tan explains.
The model developed in this research evaluates ammonia production facilities as sources and ammonia-using plants as sinks, each with defined capacities and carbon footprints. The goal is to allocate ammonia supply in a way that minimizes overall carbon emissions while adhering to the specific blending limits of each facility. In practical terms, the model successfully demonstrated system-wide substitution rates of 17.2% and 15.1% in two case studies, underscoring its effectiveness.
The implications of this research are profound. As industries grapple with the pressing need to reduce greenhouse gas emissions, the ability to seamlessly integrate ammonia into existing systems could accelerate the transition towards cleaner energy sources. This model not only provides a framework for optimizing ammonia use but also encourages companies to adopt more sustainable practices without sacrificing performance.
Raymond R. Tan’s work is published in “Chemical Engineering Transactions,” a journal dedicated to advancing knowledge in the field of chemical engineering. As the energy sector continues to evolve, the insights gained from this research may pave the way for broader adoption of ammonia as a key player in the decarbonization strategy.
